Application filed March 6, 1917. Serial No. 152,847.

To all whom it may concern:

Be it known that I, WILLIAM F. BROWN, a citizen of the United States,residing at Denham Springs, in the parish of Livingston and State ofLouisiana, have invented certain new and useful Improvements inTire-Tools, of which the following is a specification, reference beinghad to the ac companying drawings.

This invention relates to certain improve ments in tire tools and hasrelation more particularly to a device of this general characterespecially designed and adapted for use in connection with demountablesplit rims; and it is an object of the invention to provide a device ofthis general character having novel and improved means whereby a splitrim may be readily expanded or contracted to apply or remove the rimfrom applied position.

It is also an object of the invention to provide a tool of this generalcharacter havingnovel and improved means which cooperates with a splitrim in a manner to facilitate the requisite locking of the split endportions of the rim.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved toolwhereby certain important advantages are attained and the device isrendered simpler, less expensive and otherwise more convenient andadvantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitelyclaimed.

Inorder that my invention may be the I better understood, I will nowproceed to describe the same with reference to the accompanymg drawlngs,wherein- Figure 1 is an elevatlonal view of a tlre tool constructed inaccordance with an embodiment of my invention and in applied position;

Fig. 2 is an enlarged fragmentary view partly in elevation and partly insection of my improved tire tool as herein embodied;

Fig. 3 is an enlarged fragmentary view in elevation of my improved toolas herein disclosed and illustrating the end portion thereof opposite tothat illustrated in Fig. 2; and

Fig. 4 is a fragmentary view in elevation showing certain of the partsin a. second position.

As disclosed in the accompanying drawings, R denotes a split rim ofconventional construction having one end ortion provided with the tongue1 adapted to interlock with the second end portion of the rim, and 2denotes a pivot latch carried by the second end portion of the rim andadapted to coact with the tongue or extension 1 in a conventional mannerfor a well known purpose.

As herein disclosed, my improved tool comprises the reversely threadedelongated shanks 3 and 4 with which is operatively engaged a turn buckle5 herein disclosed as comprising an elongated member providedintermediate its length with a recess or open ing 6 into which asuitable implement such as a screw driver or the like may be inserted inorder to facilitate the requisite rotation of the turn buckle.

The outer end portion of the shank 3 is provided with the head 7. Saidhead 7 has the outstanding and longitudinally directed spaced ears 8between which is positioned an .andwhich hook member 15 bridges orstraddles the outer end portion of the arm 9 but separated therefrom.The outer end portion of the arm 9 and the adjacent hook member 15 ofthe arm 14 afi'ord coacting clamping jaws between which a marginalportion of the rim is adapted to be clamped especially when it isdesired to contract the rim.

' The outer end of the second shank 4 is also provided with a head 16,the outer portion of which being pointed, as indicated at 17, andprojecting beyond opposite sides of the head 16 and in longitudinalspaced relation relative to the head and the shank are the studs 18. Theouter studs 18 are directed through the slots 19 disposed longitudinallyof the metallic straps 20 while the inner studs 18 are adapted to beseated within the open slots 21 arranged inwardly of the slots 19 but inlongitudinal alinement therewith. The slots 19 are of such a length asto permit the rear studs 18 to be free of the rear slots 21 when thestraps 20 are moved forward so that the straps 20 may turn about theforward studs 18.

Pivotally engaged between the outer ends ally engaged with said ofl'setportion 24' of the straps 20, as indicated at 22, is the elongated arm23 also having its outer end portion offset, as indicated at 24, andpivotthrough the medium of a rivet 25 or the like is the elongated arm26 having its forward end portion returned to afford a hook member 27adapted to overlie or bridge the outer end portion of the arm 26 so thatthe hook member 27 and the outer end portion of the arm 23 may contactto afford a clamping contact with the rim when it is desired to contractthe rim to remove the same. When it is desired to expand a rim in orderto apply the same the arms 14 and 26, or dogs as they also may betermed, are reversed which permits the outer or free ends of the arms 9and 23'to contact with the rim so that upon the turn buckle 5 beingproperly rotated, the rim will be caused to properly expand.

In practice it often occurs that theton-gue 1 fails to properly lockwith the opposite end portion ofthe rim. In this event, with my improvedtool, the arm 23 together with the straps 20 are swung out of positionso that the pointed end 17 of the headlfi may be brought into engagementwith the tongue 1 so that said ton ue may be gently forced into placeand he d rigid until the latch 2 can be turned in holding or lockingadjustment. When my improved tool is in this position the operator hasconvenient access to the latch 2 so that the tongue may be bled, and itwill also be obvious that my 4 invention is susceptible of some changeandmodification without material departure from the principles andspiritthereof and for this reason I do not wish to be understood as limitingmyself to the precise arrangement and formation of the several partsherein shown in carrying out my invention in practice, except ashereinafter end thereof, coacting means carried by said second memberand the strap for holding said strap against pivotal movement, and rimengagin means pivotally engaged with the outer en portion of the strap.

2. A tire'tool comprising a pair of coaxially disposed elongatedmembers, means c0- acting with the inner end portions of said membersfor imparting movement thereto in a direction toward or from each other,rim engaging means carried by the outer end portion of one of themembers, longitudinally spaced studs extending laterally from the outerend portion of the second elongated member, a strap provided withlongitudinally disposed alined slots through which the studs of saidsecond named elongated member are directed, one of said slots havingan'open end so that said strap may have pivotal movement about thesecond stud when said strap is moved longitudinally in one direction,and rim engaging means carried by the strap. a y

In testimony whereof I hereunto .aflix my signature in the presence oftwo witnesses.
